Phathead Racing heads.
Benefits include: Choice of combustion chamber to adjust compression
Increased heat transfer of the billet aluminum for better performance and engine life
Increased cooling capacity of the larger two part design for better performance and engine life
Lower cost of replacement in case of failure, just swap out the chamber
O-ring design to eliminate the need for gasket(except on some big bore models)
We think they look pretty cool too
